At first, it may be a little difficult to figure out how to block a contact on the whatsapp application, but that's because the setting is not where you would expect it to be. One would think that pressing the menu button on a contact's overview page would bring up a menu containing an option to block the contact, but that is not the case. Yeah there is a menu, but it does not include the Block option.
